RubyMine 2019.2 adds support for Rails 6 and Ruby 2.7, improves YARD support and the debugger, and incorporates many platform improvements.
Our debugger used
TracePoint :line to trace the program execution line by line. For
v2019.2, we have designed a native extension for MRI that lets the debugger choose at which
fragments of code the execution should be suspended, and free the rest of the code from
overhead. As a result, we've been able to dramatically speed up the debugger and implement the
new features below.
Previously, if you stumbled across a line with lots of methods in a debug session, RubyMine was only capable to step into the first method in a line. The newly added Smart Step Into lifts this restraint and allows you to step into and investigate every particular method or a block call located on the same line.
With the new version you can set breakpoints not only at lines but also at blocks. When you click the left gutter to set a breakpoint at a line that contains a block, RubyMine will ask if you want to set a breakpoint at a line, block, or both.

RubyMine 2019.2 supports Pattern Matching, which was introduced in the first preview of Ruby 2.7 as an experimental feature. The IDE identifies the new syntax and helps you navigate, find usages, and rename the objects.
The new version of RubyMine recognizes the syntax of numbered parameters and shows/finds their usages. This is one more experimental feature of Ruby 2.7 which allows you to assign values in blocks using a parameter number as a default parameter, instead of defining a block variable.
RubyMine 2019.2 supports Action Mailbox which will ship with Rails 6. The IDE suggests autocompleting routing methods and callbacks, and navigates between their implementations and usages.
We’ve also added a couple of inspections that let you know if you’ve forgotten to add a
routing call in
ApplicationMailbox and a
method in your mailbox. The latter also offers a quick-fix.

We've added proper code insight support for
ActiveRecord::Enum. This includes code
autocompletion, navigation, and finding usages for enums’ names and methods. Negative scopes for
enums, introduced in Rails 6, are supported as well.
We’re gradually improving our support for YARD to help you create and manage YARD tags, and
get better code autocompletion in RubyMine based on YARD annotations. The new version adds
proper type annotation and inspections for

With v2019.2 you can rename (Shift+F6) factories, sequences, and traits. The IDE finds their definitions and suggests renaming it and all usages, as well as the file name if it matches the factory name.
We've also added factories, sequences, and traits to the File Structure view (Alt+F7) and popup (Ctrl + F12), and added the ability to safely delete them (Refactor | Safe Delete).
The new Propagate to destructuring intention ( Alt-Enter ) allows you to replace an extra variable if possible with another destructuring. To remove a destructuring completely, use the intention action called Replace destructuring with property or index access.
Code completion for components and their props from Vuetify, BootstrapVue, Quasar, and some other Vue component libraries is now more precise. This was made possible by a new approach we’ve adopted to working with these libraries in the IDE.
With v2019.2 you can maintain different code styles in different parts of your projects by
.editorconfig files. In addition to the standard
EditorConfig options, which have been supported for a long time, you can now use
IDE-specific properties that cover all available IDE code style options.
.gitignore files, the IDE now offers code completion suggestions for files
and folders. Ctrl-click on the name to jump to this file or
folder in the Project tool window. You can also quickly add files to
.gitignore from the Project view and Local Changes tab –
right-click on it and select Add to .gitignore.
Now you can search for data in your databases even if you don’t know where it is located. Right-click the data source that you want to search through and select Full-text Search (Ctrl+Alt+Shift+F). The results of your query will be filtered to show only those strings in which the data is found.
